Fun Facts
- 🌱 The common name 'chameleon plant' refers to the foliage's remarkable color-changing ability—leaves shift from green to red to yellow depending on light exposure and temperature, making each plant uniquely variegated.
- 🌱 In Vietnam, Houttuynia is called 'rau diếp cá' (fish-flavored leaf) and has been used in traditional medicine for over 2,000 years, particularly valued for treating respiratory health.
- 🌱 The plant is highly invasive in some regions and can spread aggressively via underground rhizomes, so it's best grown in containers or confined areas to prevent uncontrolled colonization.
